The place can be quite confusing to find - as they have another place with the same name (Siam Nitra) just nearby. We checked in wrongly; but the host did not respond to assist when we did.
The wifi network that the host provided was also nowhere to be found, and another network login details were only provided (thankfully, fairly promptly) when I asked the host to assist us.
Overall, it was an okay stay; the room is big and as pictured; but the amenities were not the cleanest - stains were found on the bedsheet and ants were crawling near the bed on the last day; though we did not have any food near our bed. The shower pictured looked fantastic; and was one of the reasons why we booked this Airbnb; but the water pressure was poor. That being said; the location is great - within minutes walk to the nearest BTS and also walkable to MBK and Siam.
Do also take note that you will have to climb up 3 flight of pretty steep stairs to get to the room.
